MOTOR-DRIVE FORr TYPESETTING-MACHINES.

Application'filed August 13, 1919.

To all whom itmay concern: Be it known that I, PABLO PAnIs,.a citizen of the Republic of Venezuela, andresident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Motor-Drives for TypesettingeMachines, of .which the following is a specification.

This invention relates to typesetting machines, especially of the character set forth in U. S; Patent No. 1,259,900, granted to myself March 19, 1918.

The object of the present invention is to provide a motor drive for a machine of this character, that will serve to convey a type selected by the depression of a key, to the chase in which the type are placed in series to produce the desired printing efiect.

1n the accompanying drawings showing one embodiment of my invention, Figure 1 is a side elevation, showing part of the keyboard and conveying. means, and selecting means.

Figs. 2, 3, 4 and 5 are similar views showingthe parts in successive positions.

Fig. 6 is a planshowing the two conveying mechanisms.

Fig. 7 is a vertical section through a portion of the mechanism.

In the drawings, 2 indicates a keyboard having keys 3 that. when depressed each en.- gages a universal bar 4 carried by levers 5 pivotedat 6. By mechanism not herein set forth each .key cooperates with a selecting mechanism, denoted. generally by 7 by which a type corresponding with the key depressed is selected and advanced to a suitable guide-way, to be conveyed by suitable conveyingmeans. Selecting means of this character are set forth in detail in my said patent.

Any suitable means or mechanism for conveying the selected type can be employed, I illustratea conveying device. that is inthe form of extensible and contractible means, such as a lazy-tong device denoted by 8. This-device is also set. forth in my said patent, andis actuated by means of links9 and10pivoted to a cross arm 11. This arm is connected with a lever 12, that is,v rocked from. a motor shaft 13*,thro ugh suitable. connecting and. driving mechanism.

The shaft 13 carries a clutch cone=14 that. is' keyed to slide-thereoniandcarries a collar 15 slidable-on theshaft and having a screw Specification of Letters Patent.

threaded bore 16 that engages a screw threaded sleeve 17 fast to the shaft frame and forms a bearing. for shaft 13. The swinging of the sleeve 15 by an arm 18 will advance the come 14 into clutch sleeve 19 fast on a sleeve 20 loose on the shaft 13.

The sleeve '20 carries an elliptical gear 21 that meshes with an elliptical] gear 22 fast on a short shaft 23. The latter shaft carries a disk. 24 having a crank pin 25 thereon, that connects with the said lever 12; a rod 26 connects this crank pin with the said lever 12. By this means each-rotation of shaft 28 will rock the arm 12 and links 9 and 10, causing the lazy-tongto ex.- pand to feed a selected type, and then con tract to normal position, as indirated in Fi s. 1 and 4.

y reason of the elliptical gear connect.- ing the driving shaft with the shaft 23, at the beginning of a revolution, from the position of Fig. 1, the shaft 23 will have. a relatively accelerated movement for the first half of the'revolution, andfor the balance of one revolution the shaft 23 will have a gradually retarded relative movement. This would result in the lazy-tong. device increasing its speed from the start, and decreasing its speed at the end of the return movement. But the crank connections lietween the shaft 23 and the lazy-tong. device will result in an accelerated starting movement, that becomes retarded at the end of the half revolution as the crank pin reaches a dead center. Therefore the lazy-tong. device will have a retarded movement. atthe As the crank the speed of the lazy-tong device, and at the latter portion of the revolution will retard the movement,.so' that the lazy-tong device will have its speed much slower. at the end of the return movement.

I further provide means whereby the shaft 13, that can be driven. continuously,

asby an electricmotor, is connected through the clutch to. impart a single revolution to the sleeve 20, and is thereupon disconnected,

and which is effected depression of. the universal bar 4. The arm 18 that serves to advanceithe clutch conezand retract.it,:.is connected by a bar 27 with a lever 2 8swinging loose on the shaft 6. A lever 32. fast with. arms 5 on shaft 6 carries ablock 29 thatengages the pivot pin 30 oflthe link 27 when the universal bar 4 is depressed iby a key, and hence the arm 18 will move downward and engage the clutch member. The lever 28 projects beyond the pivot 6 and connects with a spring 31 that will elevate the lever 28 and link 27 when the key is released, and hence withdraw the clutch cone 14.

I further provide means for causing the clutch members to engage provided the key is not given suiiicient depression to advance the clutch cone, to insure operation of the motor shaft to advance the conveying device. Arm 32 connects by link 33 with a lever 34, pivoted at 35, and which lever carries a pawl 36 arranged to engage a stud 37 on the clutch advancing arm 18. When the key is fully depressed, see Figs. 2 and 3, the pawl 36 will be positioned some distance above the stud 37, and if the key is depressed but a part stroke, the pawl will still rise to engage the stud 36, see Fig. 2. A lever 38 pivoted at 39 is connected to slotted lever 34 by stud 40, and a spring 41 serves to retract levers 38 and 34 when the key and universal bar are released. This will serve to draw down the pawl 36 from the position of Fig. 3, or of Fig. 2, that will carry arm 18 downward and engage the clutch members. i To release the clutch arm 18 from the pawl 36 at the end of one revolution, I arrange a cam 42 on the clutch member 19, see Fig. 4, that will strike an arm 43 connected with the pawl 36 by a link 44. This cam will swing the pawl 36 away from stud 37. Spring 45 draws pawl 36 pressed toward stud 37, also presses arm 43 against the clutch cam 42. i

' I also provide means for arresting the rotation of the driven sleeve 20 at the end of a revolution, which comprises a stop cam 46 fast on the sleeve 20, that engages an arm 47 havinga lug 48 thereon normally in position to engage this stop, see Fig. 1. A link 49 connects the lever 5 with the arm 47 so that when the key and universal bar are depressed the stop arm will release the stop cam and permit rotation on engagement of the clutch members. Release of the key and the rising of lever 5 will restore the stop arm 47 so that on conclusion of one revolution the sleeve 20 will be arrested by these parts.

It will thus be understood that when a key is depressechthe selecting means will first cause a type to be advanced, and thereupon the clutch members will be shifted to engage. But the link 49 will first shift the stop arm 47 to release the sleeve 20, before the clutch members engage. If the key is only partly. depressed and arm 18 is not swung to advance the clutch cone sufliciently to engage, when the key is released and the universal bar rises, the pawl 36, that will be raised on partial depression of a key, see

Fig. 2, will now serve to move arm 18 downward a farther distance to engage the clutch members. At the conclusion of one revolution of the sleeve 20 by the motor shaft 13, the trip cam 42 will swing pawl 36 away from the stud 37 and permit arm 18 to rise and free the clutch members. At the end of this revolution the stop arm 47, that rises as soon as the key is released, will be engaged by the stop cam 46 and arrest the sleeve 20.
